With big digits and high-contrast visibility, this attractive clock easily communicates the time from across a room. Hidden behind the old-fashioned dial is an incredibly precise time counting mechanism that--for extra accuracy--frequently synchronizes itself to the the national atomic clock signal. It automatically adjusts for daylight savings time, too. Requires 1 AA battery, not included.

Other Thoughts: I have bought 3 of these, though with a different face options. One of them completely stopped working after a couple of months. LaCrosse has you send it back to them at your expense for warranty. The others go through batteries much faster than other clocks. Batteries last on the order of 6 months. Symptoms of dead batteries can be stopped clock or wrong time. So, check your watch first. If it's nearly the same time as the clock, then the clock is correct to within a second. If not, get new batteries for either your watch or your clock.
